Semi-structured interviews with key environmentalists conducted in 2002 suggest strategic decision makers, organisational spokespeople and Green politicians are key leaders of the Tasmanian environmental movement, although charismatic leadership persists following movement routinisation. Routinisation is associated with the rise of non-protest environmental movement organisations addressing mainstream issues such as soil erosion, while protest oriented organisations champion the protection of old growth forests. Disproportionate federal government funding of non-protest organisations underpins tensions between movement leaders. An environmental council representing the diverse interests of the groups and organisations comprising the movement mitigates tensions and strengthens leader integration. Entrenched leaders from the 'baby boom' generation hinder the rise of younger leaders. Leader mentoring schemes adopted by movement organisations offer a potential solution to leadership succession in a mature social movement.
